I obtain this error: Error -2147217900 Specified owner name 'dbo'...

Errore -2147217900 Specified owner name 'dbo' either does not exist or you do not have permission to use it

The owner name for all the objects created by the users must be the same of the login connected to MSSQL service: it cannot be dbo because the users do not have the dbowner permissions, option possible only on your own dedicated server
